Answer:
3.45×10⁻⁴mm (or 0.000345mm)
Explanation:
Use a method called dimensional analysis here. It involves a chain of conversions, so we'll need some conversions to work with.
- 1nm = 1×10⁻⁹m
- 1mm = 1×10⁻³m
- 345nm; which is given
If you knew the conversion from nanometers to millimeters then you could just do it in one step. But I don't, so I won't. Anyways, you put the conversions into fraction form like so:
And then orient them in a way where multiplying the two (or more in other instances) gives you the units you want. In this cas it's millimeters so you'll have:
(345nm)•(1×10⁻⁹m/1nm)•(1mm/1×10⁻³m)
Notice how all the units reduce except for mm. From here you just multiply across and should get 345×10⁻⁶mm which simplifies to 3.45×10⁻⁴mm.

∠BAC= 180-110 (angles on a straight line=180)
∠BAC=70
Triangle ABC is isoceles
∠ABC=∠ACB
Sum of angles in a triangle = 180
180-70=110
110/2=55
x=55
∠BCA= 55 (bottom angles are equal)
180-55=125
y=125
V=IR. So if voltage V is the same but R goes up, current, I, must go down for the equation to remain true.
